The solar water heater controller is four wires. The sensor is two wires how to connect 30

The operation is as follows: 1. Solar water heater.

The sensor includes two parts of water level and water temperature, which are two lines for a total of 4.

2. It cannot be connected together, otherwise the water temperature and water temperature of the instrument will be incorrect.

3. Generally speaking, there are 4 small holes in the square joint of the sensor to the degree instrument, corresponding to the 4 pins of the instrument, and the wrong connection is: display temperature.

4. Ask that there is no water level and no temperature is displayed, and there is no water level without temperature, and there is no water level display. You can switch the 4 wires repeatedly until there is a temperature and water level and it is normal.

It's better to change the sensor, preferably with the original factory.

There are so many brands and types of controllers and sensors on the market today that they can't actually be used with each other. With different sensors, the parameters on the inside of the meter need to be adjusted. Otherwise, there will be a situation where the water runs out or the top half of the bucket of water.

Can you tell us about the model of the controller or the brand of the solar water heater? It's best to have a sensor model, because each manufacturer's is different! In fact, the solar water heater you bought should have a connection method on the manual, you can take a closer look, there is a detailed circuit diagram on the manual of my water heater.

Change a four-core sensor or a four-core or two-core instrument, the four-core instrument and the two-core sensor are not matched. No, it can't.

The red line of the 4 wires of the controller is connected to the red and white lines of the sensor, and the other 3 wires are connected to the yellow line of the sensor.

Can a four-core wire be changed to a two-core wire?

The PLC needs to have a positive power supply at the common end, a positive power supply at one end of the sensor, and a positive input at the PLC input end. If the PLC common end is power negative, then the sensor needs to be connected to the PLC via an intermediate relay.

Transducer sensor is a detection device that can feel the measured information, and can transform the felt information into electrical signals or other required forms of information output according to a certain law, so as to meet the requirements of information transmission, processing, storage, display, recording and control.

The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-function, systematization, and networking. It is the first link to realize automatic detection and automatic control.

The existence and development of sensors allow objects to have senses such as touch, taste, and smell, allowing objects to slowly become alive. It is usually divided into ten categories: thermal elements, photosensitive elements, gas-sensitive elements, force-sensitive elements, magnetic sensitive elements, moisture-sensitive elements, acoustic components, radiation-sensitive elements, color-sensitive elements and taste-sensitive elements according to their basic sensing functions.

Summary. Hello, 2: The green wire and the white wire are connected to the temperature sensor, which transmits the real-time temperature to the motherboard and the display board through the temperature sensor, so that we can know the current temperature and facilitate the motherboard to receive and receive signals.

2: The blue and red lines are connected to the water level sensor, and the resistance is about 60k when not put into the water. The function is to detect which height the water in the tank is now, the water tank has an upper limit, when it is greater than this height, you need to stop adding water to the tank to prevent overflow.

These 2 wires are the water transmitted to the motherboard, and now the water tank has reached the upper limit, and you can stop adding water.

How to connect the four wires of the solar water heater sensor.

Hello, 2: The green wire and the white wire are connected to the temperature sensor, which transmits the real-time temperature to the motherboard and the display board through the temperature sensor, so that we can know the current temperature and facilitate the motherboard to receive and receive signals. 2 roots:

The blue and red lines are connected to the water level sensor, and the resistance is about 60K when not in water. The function is to detect which height the water in the tank is now, the water tank has an upper limit, when it is greater than this height, you need to stop adding water to the tank to prevent overflow. These 2 wires are the water transmitted to the motherboard, and now the water tank has reached the upper limit, and you can stop adding water.

These 2 wires are the water transmitted to the motherboard, and now the water tank has reached the upper limit, and you can stop adding water.

There are four threads, red, green, blue, and white.

Also: red, green, blue, yellow.

It's all four threads.

2: The green wire and the wire are connected to the temperature sensor, which is used to transmit the real-time temperature to the motherboard and the graphics board through the temperature sensor, so that we know the current temperature, and the motherboard receives and receives the signal. 2 roots:

The blue and red wires are connected to the sensor, and the resistance is about 60K when not centered. The purpose is to detect which degree the box is in now, and the box has an upper limit, and when this degree is reached, it is necessary to stop adding to the box to prevent overflow.

Hello, the solar water heater controller is connected to the sensor Sique Brigade Root Line is connected to the following two wires: the sensor of the solar water heater includes two parts: water level and water temperature, which are two lines for a total of 4, which can not be connected together, otherwise the water temperature and water temperature of the instrument are not displayed correctly. Generally speaking, there are 4 small holes in the square joint from the sensor to the instrument, corresponding to the 4 pins of the instrument

The temperature is displayed, no water level does not display the temperature, there is no water level and no temperature is displayed. You can polyphonize the 4 threads until there is a temperature and water level that is normal.
